To all whom totaly concern.' y

Be it known that Lftlaakon A. Mannini', a citizen of the United States,residing at Dayton, Vin the county of Montgomery and Sta-te of' Ohio,have invented certain 'new and useful Improvements in Casirllegisters,of which I declare the following to be a full, clear, and exactdescription. y

This invention relates generally to ac counting machines and theparticular thereof.

One ot' the objects of this invention is to obtain a4 better form of keycontrolled differential mechanism, `which subjects the mechanism of themachine to less jars than the known forms and the operation of which ismuch smoother in action. In the illustrative form of the invention shownherein this 1s accomplished by providing adjacent each bank 'of amountkeys a disk having'an oscillatory movement of invariable extent at everyadding operation and adapted to drive differentially a gear employed toactuate the corresponding units of the accounting printing andindicating mechanisms. The extent of movement of theactuating gear islimited by the engagement of a roller ona latch plate carried by thegear and normally conneoting the disk and the gear together, with a camedge on the key depressed, which thus serves to operate the latch. plateand render 1t m'eectlve as a connecting member be `tween the disk andthegear. `The disk continues its movement uninterrupted and upon its returnmovement the latch again couples the disk and the gear together andcauses the latter to be restored to normal position i with the disk.

'It is a further object otthis invention to have a cooperativerelationship established. between the tota-lizer and differentialmechanism by the same means and at the same timein a turn to zerooperation as in an adding operation. l In the preferred form ol theinvention embodied herein this Send is obtained by always throwing thetotalizer into mesh with the actuators at the beginning of the operationof the machine and moving the differential mechanism to either side ofnormal position without changing the direcembodilnent shown and.described to that class' tion of: movement ci the main. driving mechnanism. This permits of acciilmulating on the totalizer the several zint-sy indicated by the indicators and printed by the, pr i ingmechanisnn when moved in one directioln and ot turning the totaliaer tonero and printing the totals originally on the totaln izer on recordmaterial when rotated in tliie reifeirse To t :l a "totrrl. k i isprovided which, 'n n depressed, remlersinctl'ec ive to drive the ditferential mecha In in an adding direction,

connections between the main drive ifty and the shaft carrying thedriving disks, and renders the connections eil'ective to drive thedifferential mechanism in a reverse d1- rection for turn to Zerooperations.

Another object of the invention. is to construct the totalizer and thetrzrnst'er mecha nism to effect a transfer when required dur` ing anadding operation of the machine, and to control. the differentialmovement of the differential mechanismpin turn to zero or total takingoperations. The totalizer includes a` pliilrality of totalizer pinions,one adjacent each actuating gear, and carried by a bell crank leveradapted to be oscillated at all operations of the machine to throw thepinions into mesh With the corresponding actuating gear. The transfermechanismincludes transfer pawls mounted on bell crank levers oscillatedsuccessively at each operation of the machine from a series of cams. Thepawls on these levers are adapted to be moved into tripped position tosubsequently effect transfers, by levers mounted on arms secured to apivotal plate with a circular' recess into which a roller projizmtingfrom the latch plate connecting the driving disk and the differentialactuatear, passes. These levers are moved 'to p the transfer pawls bylong teeth onthe t. liner pinions as the latter pass from nine to zeroposition. As the totalizer pinions are rotated backwardly in a totaltakin g op eration the long tooth on each lviinion abuts 11st the 'Y Yl.l ill drive them. The form of mechanism herein v pinion, positioned'shown is highly adapted for use in the particular machine disclosed butit is to be understood that the form is illustrative only as theinvention is susceptible of embodiment in other forms. The constructionused employs two adjacent and similar pinions, loosely mounted on ashaft, one of the pinions is continuously in mesh with a pinion actuatedby the differential gear and the other is continuously in mesh with thepinion integral with the indicator wheels. Rigid on the shaft supportingthesekpinions are-arms carrying at their outer endsa hori- Zontal barpassing through slots in all the adjacent pinions and concentric withthe shaft supporting these pinions. A third pinion fast upon the shaftmeshes with a segmental rack, actuated at the beginning of eachoperation of t e machine, and before thc differential mechanism isactuated to set the indicators to zero position by a cam on the maindrive shaft. A pinion actuated-by the main operatingmechanism isprovided to couple the adjacent pinions together so that they may movein unison upon movement of the differential mechanism for all addingoperations of the machine.

Itwas a further object of the machine to 'provide means whereby theindicator does not indicate upon a turn to zero operation of the machinethe total which stood on the totalizer at the beginning of theoperation.

One of the means by which this object is effected is disclosed hereinand comprises mechanism for to be thrown into engagement with the pinionmeshing with a pinion integral with the indicator and the-pinion meshingwith the actuating gear, inoperaated by the operation of a tive during atotal taking operation. This mechanism includes a detent which isactutotal key and employed to render the connections between thecoupling piniony and the main driving mechanism ineffective upon thedepression of the key.

lVith these and incidental objects in View,

the invention consists in certain novel features of construction andcombinations of parts the essential elements of which are set forth inappended claims, and a preferred hereinafter described with reference tothe drawings which accompany and form part of this specification.

Of said drawings z- Figure 1 is a'transverse vertical section of a cashregister constructed according to this `invention showing correspondingunits of the differential, indicating, transfer mechanisms. A

and slidable in ways cut in the flanges 3 and 4r. projecting from theframe 2 at its outer rand inner periphery. The keys are normallyelevated by springs 5 engaging beplates 6 integral with the key Shanks7% and above thevflange 4. Each key on its left side is provided with apin 8 (Fig.

normally in position to engage an inclined edge 9 of a key lockingdetent 10 when a key is depressed. The detent 10 is provided at bothends with elongated lnotches 1l through which pass the shaft 12 and tiebar 13 extending laterally through the machine and supporting the frames2. Upon depression of a key Vitsfpin 8, by engaging the inclined edge 9of the detent 10, lifts the latter to p ermit full depression of thekey. The

key 1s retained in' its depressed position dur- I ing the operation ofthe machine by the detent 10 Which for this purpose is provided withnotches 14 at thelower ends of the inclined edges 9 so that when thepins on the spring 15 and a pin the detent to enpin 8 on the del7y-0nthe frame 2 returns gage the notch 14 with the pressed ke j Inl addition-to the usual amount keys a zero stop 18j is` provided in each bank aswith the particular differential mechanism employed herein it isnecessary to prevent the driving \mechanism from im parting a movementto the differentialfactuating mechanism ,when none of the amount keys inthe bank are depressed. The con- `aguide pin passes.

struction of this stop 18 is nearly identical to that of the amount keysl except that the number carrying top is omitted, and itis lprovidedwith a slot '19 through which is depressed yit is desirable to renderthe zero stop 18 inoperative and to eiiect this one end of a bellcranklever 20, (Figs.

Q and. 3), centrally pivoted at :21 to the frame 2, pivotally connectedby a pin 22 to the detent l0, the other end of the bell crank lever 20being pivoted at 23 to the zero stop i8. The depression of an amount keyby lifting the detent 1() carries lthe pin Qdi, priijecting from thedetent and positively retaining the zero stop in. its normal position,out of operative relation with, the forward end of the stop and rocksthe bell crank lever 20 clockwise, thus lift ing` the zero stop 1,8outward from the operative position shown in Fig. 3. Carried, on theright hand side oi? ythe shank of each amount key and Zero stop, is theplate G havin a cam edge 7 which, when an `amount `key is depressed, orthe-zero stop retained in its operative positiomis in operative positionto control the differential mecha nism.

Dije/enzimi mechanism.

The differential mechanism comprises a x the pinion 33 through whichtype carriers are positioned and, it also actuates correg spendingdenominational pinions 34 of the totalizer when they are rocked intomesh with it. The indicating, vprinting and totalizing mechanism `willbe hereinafter fully described.

The driving mechanism of the machineV includes a drive shaft which issuitably mounted in bearings on the side frames 30 and 3l of the machineand given in any desired manner at each `operation of the machine onecomplete rotation clockwise as viewed in the drawings. The shaft 29,which is oscilla-ted about 75 degrees in a clockwise direction by themain `drive shaft 35 through connections intermediate itand Ythe maindriye shaft for an adding operation, is also lcapable of beingoscillated a like extent of movement in the opjiosite I directionthrough these connections in a .manner to be hereinafter explained for atotal taking operaticm. i Fast upon the rock shaft 29 'and at the sideof thelactuating gears 28 are disks 38 each of which has a.

lVhen an amount key- 4holds the latch in its normal position.

notch 39 in the rear portion of its periphery. A latch plate 40,parallel to and adjacent a side of the disk has a slot 41 through whichthe shaft 29 passes. The latch is connected. to the gen1-2S by theeng-.igen'ient of a pin 42 on the gear with the slot L3 in the latch 40the latch, being thereby allowed movement radial to the gear 28 and thedisk 38. The latch carries at its forward end an anti-friction rollerLlei nor mally in engagement with the lowerifend of the cam edge 7 onthe plate (i on the Zero stop 18, and at its rearward end has alaterally and forwardly projecting lug 45 normally resting in the notch3.9,in the periphery of the disk 38. .A tensioned spring ab connected atone end to the hook e7 on the` latch and at the other to a pin 28 In anadding operation oi' the machine, when no key is depressed the latch 40,upon the @i8 projecting from the adjacent gear irst onedlalf unit ofmovement oi" the disk A38 is forced rearward .against the action of thespring 46, as the roller il rides forward on the cam edge 7 of the plate(i on the zero stop and this inner movement of the latch is suliicientfor the "lug 45 to clear the notch 39 in which it is normally locatedand permits continued movement of the driving disk 38 in a clockwisedirection independent of the actuator 2S. atorfis brought to rest andheld in such position as the roller 44 on the latch is vfirmly retainedbetween the cam edge 7 and the curved recess 49, which is oppositethezero stop 18 and vin the 'eripheryI of a circular plate concentric Witthe rock shaft 29 and mounted onv the key `bank frame 2 by screws 51. p

The depression of a. key `carries the zero stop out of operativeposition, as has been heretofore explained, and the actuating gear isdriven upward more or less byl the driving disk before it is stopped' by`the engagement of the roller 44 with `the edge 7 of the cam plate 6 ofthe depressed key, the cam edge iaving been moved into the path of theroller by-the depression of the key, and the roller being thereby firmlyretained between the cam edge and a recess y The actu- 49y opposite thekey in the curved plate 50.

In this way any desired differential'move-g ment is impartedto theactuatingge'ars 28 by driving mechanism which has"` aI constantvmovement. The normal position of the roller 4l on the latch 40 isone-half unit `of movement below the center of the zerostop 'i 18 andaccordingly the disk 38 'gives the yactuating gears 28 one-half unitofgmove ment before the latch plate Il() is inner movem nt to disconnectit iven van rom the disk 38. 'Provision is made initheindicating,'accounting, and recording mechanism whereby these mechanismsare unaffected by this idle movement of the differentialactuators 38, aswill be hereinafter explained.

After the driving disks 38 have completed their movement in a clockwisedirection and before they begin their return movement the keys arereleased and when the notches 39 on the driving disks upon their returnlnovef ment lare. again oppositethe lugs on the latches i0, the latchesthrough the springs 46 will be pulled forward and the disk with theactuating gear returned to zero position as afunit. The amount keys arereleased as the driv.ing disks 38completeI their excursion'of movementin a clockwise direction. To this end open cams 5l beside the detentsand rigidly mounted on the shaft 12 supporting the lower ends of thedetents arel provided. A single arm (Fig. 8), fast to one end of thisshaft 12, is pivotally connected at yits lower end to a pitman 56 (Fig.6) which cannot be seen in Fig. 8 as it is similar to and immediately tothe left of a itman 356. The pitman 56 at its rear end' 1s forked andstrad'dles the main drive` shaft 35 and carries an anti-friction roller58 (Fig. 6), riding in acam groove 59 in the face of a disk 60 rigidlymounted on the main drive shaft 35. The configurationof this groove issuch ythat upon every rotation of the main drive shaft and beforethedriving disks 38 begin their return movement,

the pitman 56 is given a rearward movement Ain the direction of itslength, and the open cams 54, rigid on the shaft 12 and thereforev withthe arm 55, are rocked in a counter-l clockwise direction engaging pins61 pro-4 jecting latex-:fly from the lower end of the detents 10. Thelatter are' thereby raised sufficiently to move the notches l in theinclined edge 9 out of engagement with the pins 8 on the depressed keyslto permit the keys to be restored to normal position by the springs 5coiled about their Shanks.- 'By this construction restoration of thedepressed up of the actuating gears 28 by-the driving `disks 3S forreturning the former into pocounter pinions, one adjacent each bank oflkeys is providedfor-prior to the picking sition for the next operation.-

Coil/Itter transfer mechanisms. VThe totalizer comprises. a plurality ofkeys, and looselyimounted on a--shaft68 supported by the arms 69 rigidwith a shaft 7 0 extending laterally through the machine.v At thelefthand end ofthe shaft70 and rlgid therewith isv a-n arm 71 which atits lower-end, is pivote-dat 72 to a pitman 73, (Fig. 4'). This pltmanisbifurcated at 'the vother end and straddles the main drive shaft 35and also has an antiff'riction roller groove '75 in the face ofa disk 76fast to the driveshaft v35. The i cam groove'is so shaped as torock thetotalizer pinions into mesh with the Aactuating 74 playing in a earngears 28 through the arm' 71 and the pitrnan 73 after the actuatinggears have moved one-half unit of movement from normal position in orderthat the totalizer elementsl may not belactuated by the geans 28` untilafter the gears have been given the-ironshalfunit of idle movement.'llhe pawls 67, the rear ends of whi are held ink engage.

ment with the totalizer pinions34 by the A springs 66 connecting thevforwlard end of" the pawls and theI arm 71, are employed to aline'thepinions in thelr various posltions.V

As the main drive shaft 35 is always rotated in a clockwise direction itis evident that the totalizer pnions are thrown -into operative relationwith the actuating gears upon the movement'of the actuating'gears fromnormal position upon every operation of the machine.

The counter transfer pawl 78 is pivoted on the'rearwa'rd end of an arm'79 by the pin 80,` the arm beingv loosely mounted on the shaft 81extending longitudinally through the machine and supported by the sideframes 30 and 31of the machine. EX- tending downwardly and rigid withthearm 79 is an arm 8.2 pivoted at 83 to a pitman, 84 (Fig. 1 which, at itsrearend, isfo'rked Vover the main drive shaft 35 and carries ananti-friction roller 85 playing in a vcam groove 86 inthe faceof a disk87. The arm 79 carries a spring pressed plunger`88, the

uppei` inclined edge 89 of whichis normallyV in engagement with vthe`lower inclined edge of a nose 90 ofthe transfer pawl 78 and thetransfer pawl is therebyno'rmally held out of operative 4position toeffect, a transfer (Figs. 1 and 4). The upwardly extend-4 ing nose .91`of the trip pawl 92, normally in engagementwith the rear edge of thetrans- 11.0.5 fer pawl 78, is adjacent the totalizer.pinion.'- v

of next lower denomination' and isnormallyl in the path of a long tooth93 .onthe totalizer pinion. As the pinion passes from its nine to itszero position, the'long Vtooth 'by its engagement with the correspondingtrip ,pawl rocks the transfer pawl 78 into trans-v ferring position.This trip pawl 92`is'sup-pported by the stub shaft 94 carried atthe gupper end of an arm 95 loosely mounted on the shaft 81. A lever 96 isalso pivoted tothe arm 95 by the stub shaft 94 and at its forward endcarries a right angied'slot 97,5

tact with a pin 98 projecting' from the eX- treme end of an irregularlyshaped plate 99' pivoted to the shaft 100 supportediby the 'side frames30 and 31 ofthe machine. To the lower end of the'leveris connected oneend of a spring 101 which, at its other end, is secured to a hook: 102mounted on ay sleeve 103 "surroundingithe'main drive shaftv vThe lowerend of the lever also carries an vanti-friction roller 104'with which anopen cam 1,05, rgidlymounted on the main drive the. upper part of whichis normally inncenter the lever 96 slot 97. The open cam tions and whilethe dwell portion 1128 of the cam groove 128 is in coperation with theroller 127 on the pitman 112 which drives'the shaft 29 at the beginningof the operation of the machine and such engagement is maintained duringthe clockwise movement of the gears but after the gears have come torestand before they begin their return movement the totalizers arerocked outl of engagement with the gears.-

VVhen, the totalizer is so rocked into mesh, the lever 96 andthe arm 95and therel'ore the trip pawl 92, being carriedby the arm 95 are rockedabout the shaft 81 as a pivotal being connected to the arm 69,supporting the totalizers,` by A4the springy 107. Whenthe long tooth 93,the totalizer being now rotated in a counterclockwise direction, engagesthe lower face of the nose 91 of the trip pawl 92, the transn fer pawl 78 is rocked about its pivotal center S0and as the lunger 88 passes outof operative relations tip with the lower edge of the nose 90 of thetransfer pawl its lower edge engages the upper edge of the nose andholds thetransfer pawl 78 in transferril'igr position.vv TWhen thetotalizer is thrown into mesh with the actuating gears the leverl 96 isrocked about the stub shaft 94 through the spring 101 and the pin 9Senters into operative relationship with the setof 108 of the 105 is sotimed that when the"totalizers are tobe restored to normal position, itengages the rollerj104 on the lower-end of the lever 96 and lrocks thelever so that the set o 108 is taken out of engagement totalizers towith the actuating be rocked out of engagement y gears without affectingthe vpivotl plate 99. After the amount has been accumulated on thetotalizer and it has been rocked back to normal position through the camgroove 7 5 in the disk 76, the transter pawl 78 is actuated Yfortransferring purposes by the cam groove 80 in the disk 87 through thepitman 84 and the arms S2 and 79 asthe forward'end of this pawl after ithas been tripped, engages the teeth on the tot'yalizer pinions.4 As thepinion is moved, this additional step the tooth on the totalizfzerpinion next to the tooth engaged by the transfer paw] engages the upperend of the 'forward edge 109 of the transfer pawl rockwith the pin 98permitting the nected by af pin 120 to a link 121 afroller 127 playingin ing the pawl in a counter-clockwise direction and thereby causing theplunger 88.to .engage the lower edge of the `nose 90 of the trip pawl 78so that the transfer pawl is rendered inoperative for transferoperations until the pavvl is again tripped. It is understood of coursethat there is one cam 76 for each transfer pawl and that these cams areso designed as to 'rock the transfer pawls successively. i

-`Tur/n to @aero mechanism.

ln item entering operations the actuating gears 28 are oscillated asjust described first in a clockwise direction during this movenientactuating the totalizer pinions 34. The machine is adapted however,

tion of the machine and set the type carriers 62 4in correspondence withthe extent of rearward movement of the counter wheels so that animpression may be taken .upon a detail strip 110 to record the total onthe counter at the beginning ofthe operation of the machine. To this enda total key is provided, the depression "of which controls connectionsbetween the ,main drive shaft 35 andthe rock shaft 29 so that the lattermay be given an oscillation of a like extent reverse to thatvvhich it'ihas on anadding operation. y I

Referring to Fig'. 8 t'v-hich shows 'this mechanism controlling thedirection of oscillation of the vshaft 29-, l 111 represents a tot-alkey which is next to the last bank of amount keys on the left of themachine. When the key is depressedzthe pin 112 pro jecting fromthe sideof the'kkey engages the inclined edge 113 in the detent 114 and slightlyraises the detent. The detent is constructed similarly to those providedfor the amount key banks and is raised against the action of a spring115 connected at one end to a hook 116 integral with the detent and atthe other end to a pin 117 projecting from' the key bank frame 118..

key when operated 1n its depressed position bv'the engagement ofthenotch 119 1n the edge ,113 with the pin 112 on the key,

111 at its inner end is conivotally connected at its'other end'by a pin122 to an arm 123i, which is loosely mounted' upon the rock shaft 29 butintegral with anarm 124 projecting inwardly and downwardly from theshaft29. At the outerendof this latter arnifis ailaterally projecting pin-125 passing ipto a slot 126 in the which is forked at .its lower end andstraddles the main drive shaft 35 and also carnes a cam groove128 in theface of a disk 129 rigidly jounaleid to the drive shaft 35. The upperend of this 'pitman is yoked, the arms 130 and 131 of The total key theyoke having notches 132 and 133 at their to turn the vcounter wheels tozero position by an opera- The detent retains the I outer ends and atright angles to the length of the pitman. AThe notch 133 in the arm 131is normally in engagement with a stud 134 rojecting from the outer endof an upwardly extendilg .arm 135 fast to the rock shaft 29. It canreadily be seen that with the pitman so connected to the arm 131rotation of the main drive shaft in a clockwise direction oscillates thearm 135 and therefore'the rock shaft 29 in a clockwise direction andthis is the direction in which the shaft is rocked for an addingoperation. In total taking operations, however, depression of the totalkey 111 through the link 121 and the arms 123 and 124 shifts the pitman112 so that the notch 133 on the arm 131 is carried out of alinementwith the stud131 and the notch 132 in the other arm 130 of the yoke onthe -pitman is thrown into operative relationship with a stud 136 on anarm 137 similar to the arm 135 4but projecting outwardly and' downwardlyfrom the rock shaft 29 to which it is fast. When the cam disk 129isrotated the pitman will be given a reciprocating movement of the sameextent as in an adding operation and therefore the shaft 29 will Vbegiven. about 7 5 degrees of movement in a reverse direction.

Referring to Fig. 3 it is evident that when the. total key is depressedthe operation of themachine oscillates the driving disk 38.

fast upon the shaft 29, in a counter-clockwise direction. The roller 44on the latch 40, normally connectingthe driving disk 38 and theactuating gear 28 is normally intermediateits zero positions that isthepositions which operation of the latch would not effect theaccounting mechanism, the zero4 position in a turn to zero operationbeing at the first curved recess I19in the circular plate 50 adjacent toand below the curved recess with which the zero stop 18 cooperates toretain the latch plate in its Zero position in an adding operation whenno` amount key is depressed-inthe bank. The tota-lizer is not enga ed bythe. actuating gears 28 until after t e first one-half unit of movementof the driving mechanism and consequently this idle movement of thegears does not result in-rotation of the totalizer pinions. i

Rotation of lthe actuating gears 28 after the totalizer pinions 34 havebeen thrown in engagement with them by the cam 7 5 effects throughcounter clockwise movement of the actuators clockwise movement of thecolinter pinions. This reverse movement of each totalizer pinion isadapted to be stopped.

when the latter has passed one step or unit beyond its zeroposition, bythe engagement of the long'tooth 93 on the pinion against the end of thenose 91 of the transfer tripping pawl 92. The long tooth on the pinionengages the trip pawl 91 when it reaches zero but one more step or unitof movement laterally from the rear end of the latch 405 lVhen atotalizer pinion is moved one step beyond its zero position and thelever 9Gy lowered, as just explained, the plate 99 because of theengagement of the pin 98 with the set off 108 of the slot 97, is carriedrearward about the shaft 100. The lug 45 on the latch l10 is therebytaken out of oper-.1- tive relationship with the notch 39 in theperiphery of the driving disk 38 as the latch is given an innermovementthrough theengagement with the forward wall of the recess 140with the` latch roller 141. The driving disk 38 is then permitted tocontinue its invariable extent of movement in a counter-clockwisedirection and at the end of 'its return moven'ient the total key isreleased hy the engagement of the cam edge 354 of an arm 355 loose onthe shaft'12. with a pin 361 on the detcnt 114. The arm 355 is rockedcounter-clockwise after the actuators have returned home to raise thedetent, by -the cam groove 359 which is formed in the right hand face ofthe disk 129 and into which a roller 358 on the pitman 356 plays', thepitman being connected at its .forward end to the arm 355 by the pin357. The totalizer is rocked out of engagement with the gears to normalposition,

as inthe adding operation, as the cam disk l 76 which controls the timeof engagement ofthe totalizer, is rigid with the shaft 35 and thereforehas the same direction of movement in both the adding and turn to zerooperations. 'When the totalizer is rocked out of engagement each pinionis turned counter-clockwise one step to zero position as the long toothis in engagement with the trip pawl 91 which with the lever 96 has beenpreviously lowered when the tooth passes beyond its zero position. It isclear that the totalizer'pinions and therefore the actuating gears havemovedmne step farther in a turn to zero operation than .they were turnedduring the accumulation The printing mechanism 1s con-` of items.structed to provide for this extra unit of movement as will be presentlyexplained.

Printing machen iam.

' 'one teeth are mounted respectively on nested sleeves 144 supported bythe shaftlet and `,are continually in mesh with the actuating gears, thetype wheel G2 being imounted on the outer end of these sleeves.` Each ofthese type wheels is previdedwith two series of types, one series beingconsecutively ar ranged going upward from the printing line,from .0 to9. A blank of one type space is normally one-half unit of movement tothe left (Fig. 9) of the printing line and between this line and the 0of this series. This series is employed to record totals in turn to zerooperations as the actuators are rotated in a counter-clockwise directionand the blank space is provided as it will be re called that theactuators are moved one extra step as the totalizer pinions move onestep beyond zero position. The type of the other series are arranged inthe same order beginning with 0 to the right of the blank space of theother series and one half-unit to the right of the printing line (Fig.9) the characters then running upwardly from l to 97, and this series isemployed to record the items in adding operations, the Vactuators ineach operation being oscillated in a clockwise direction..

This cam plate is integral with the pitman 1.55 which I n y u l 1sforked over the drive shatt 5 at its rear ,end and suitably mounted tohe` reciprocat-ed guided by a stud 15G projecting from the frame 31 andjpassing into a slot157 in the Reciprocating vmovement is imparted tothe pitman 155 by the engagement of the rollerj158 on the pitman withthe cam groove 159 in the face of a disk 160 fast to the shaft 35.Forward movement of the pitrnanforces the platen 148 against the typecarriers through vthe engagei'nent of the cam plate' 154 with the loweredge 152 olf the `plate-.n carrying bar 149. VA spring 161 ennnectinghook 162 yintegral with the platen carrying har 1419 land a stud 163projecting `from the frame 31 is provided to restore the platen tonormal position after an impression has been made on the `(hitail strip`110.'`

The detail strip 11() passes from a` Supply the ratchet 169 on the roll168 and this army" carries a pawl 17 3 held in engagement with theratchet teeth by the compressed spring spo 174 between the pawl 173 anda pin 175 on the arm 17 2.

y The indicators 179 (Figs. l and 10), are loosely mounted upon asha-'ft 180 extending longitudinally through the machine near the topand as the indicators are duplicates of each other ay description ot'the operation ol one will besuliicient. ln Fig. 1() the indicators areshown. as being nllnibered at their periplieries from t 0 to "9, and ascarrying at their sides pinions 181 `also co*- axial with the sliaft180.l `Each of these pinions 181 meshes with a gear 182 loosely mounted upona shatt 183 supi'iorted .by bearings in the side frames of the machine39 and 31 and are identical to the companion gears 184: loosely moimtedat their right side on the. shaft 183and meshing Withf the gea-r 32which, in turnymeshes with the ac,- tuating gear 28,. Inporder that anitem en@ tered on the accounting device may be set up on theindicators,coupling pinions 186 are provided each pinion being adjacentto and as wide asa corresponding palr of com-` panion pinions'182 and184. Each couplil'ig rying at its inner ei'ida-pinll() norniallyhin/ ooperative .relationship with a notch forset oit' 191 1n the upper end ofthe rear walt of slot 192 ina pitman 193. At its lower end,

the pitman is forked and straddles the main drive shaft 35 (Fig. 7), andalso carries a roller 194 which rides in groove 195 inthe face of thedisk 19o rigidly mounted on the main drive shaft The construction ofthis cam groove is such as to reciprocate the pitman 193 after the firstone-half unit of movement of the actuating gears 28 in order to providefor the one-half unit of idle movement of ther actuating gears. Thecoupling pinions 186 are thereby thrown into mesh during an addingoperation with their co1"- re'sponding pairs of pinions 182 and 184during the movement of the actuating gears in a clockwise direction fromzero position.

From the above description it is apparent that the amount entered on thetotalizer is set up on the indicators as rotation of the pinion 32 bythe actuating gear 28 rotates the pinions 182 and 184 in unisonl beingcoupled together, and therefore differentially rotates the indicators,the gear 182 being continuously in mesh with the pinion 181. integralwith the indicator wheels.

AS itis desirable to actuate the indicators only upon an addingoperation and to set the indicators to zero position at each operationofthe machine, the plnlons 182 and 184 are only coupled together andlnoved in unison during the differential movement of the .actuatinggears 28 in an adding operation.

To this end the pitman 1 93 is rendered ineffective for a total takingoperation to oscillate the arm 187 supporting the coupling pinious asthepitmanis shifted backward so that the pin 190 on the arm 189 rigidwith rthe shaft 188 may play in the slot 192 in the pitman. This pitmanis shifted rearward upon the depression of the total key by the movementof the detent 114 as the detent is connected at 196a to a link 195, theother end of the link being' pivoted to the upper end of the pit-man193by the pin 101) projecting from the link and passing into the elongatedsl'ot 200 in the pitman 193. 4

As has been stated, it is desirable to restore the indicators to zeroposition at the beginning of each voperation as otherwise with theparticular form of actuating mechanisrn described the indicators wouldaccumulate the items upon adding operations. To turn the indicators tozero the gear 182 meshing with the pinion 181 integral with theindicator is turned reversely at the beginning of each operation of themachine and independently of its associated gear 184 by the mechanism tobe now described. As shown in Fig.v 1 a pinion 203 is rigidly mounted onthe shaft 183 supporting tlie gears 182 and 184 and is constantly inmesh with the teeth of a segment arm 205 loosely mounted at one end ofthe machine on the shaft 188 but rigid with a rearwardly proto a pitman208. As shown in Fig. the' pitman 208 is forked at its lower end overthe main drive shaft- 35 and carries a projecting anti-friction roller209 riding in the groove 210 of the box cam 211 fast on the drive shaft35. Fast to both ends of the `shaft 183 are forwardly projecting arms212 carrying at their forward ends a bar 213 which passes throughcircular slots 214 in all the pinions 182 and 184, the circular slotsbeing concentric with the shaft 183. The timing of the cam groove 210 issuch that during the first one-half unit of movement of the actuatinggears 28 the pitman is given a short downward movement to rock thesegment arm 205 in a clockwise direction. The

stored to normal position upon the return movement ofthe actuating gears28 in the previous operation of the machine. The arms 212 are thenrocked to normal position by the `cam groove 210.

Operation- To operate the machine for indicating and recording theamount of a transaction and entering the amount in the totalizer, allthat 'iS necessary is to depress the proper amount key' and give thedrive shaft 35y one complete rotation. The drive shaft 35 may be rotatedeither by a crank suitably geared to it or by a motor. which is alsocommon in the art. Depression 'of the amountv keys positions their camplates 6 in the path of the rollers 44 on the forward end of the latches40 radial with the actuating gears 28. Rotation ofthe drive shaftoscillates the driving f disk 38 about 75 degrees in a clockwisedirection, as viewed in the drawings and each disk being connected toits adjacent actuating gear 28 by the latch 40 through the engagement ofthe pin-42 on the gear 28 in the slots 43 in the latch and the restingof the lug 45 on the rear end of the latch in the notch 3S) in theperiphery of the disk7 carries the gear with it until the roller on thelatch engages the cam plate 6 on the depressed amount key. Suchengagement imparts to the latch a radial movement and disconnects thedisk 38 from the gear 28 by theclearing of the lug 45 from the notch 39inthe disk after which the disk is allowed tocontinue its clockwisemovement inde endeht; of the` actuator. During the di erential movementof the actuators just referred to the counter pinions 33 are rocked intomesh with them through the oscillation of the counter frames 09 aboutthe shaft a pivot effected by the cam. groove inthe disk 7G fast tothemain drive shaft. Afterthe time for the differential movement of theactuators has elapsed, the counter pinions are disengaged from theactuators and ,the depressed keys are released. Each actuating gear isthen subsequently picked up upon the return movement of itscorresponding disk and moved into position shown in the drawings for thenext operation as the cam plate 6 of the depressed key has been movedout of engagement.

with the rollers 44 on the latch plate upon the restoration of the keytonormal position the latch Vbeing then pulled forward by the spring 46when the recess 39 in the disk comes opposite the lug 45 on the latch.After the totalizer is disengaged from the actuators the transfer paWls78 are successively rocked clockwise by the box cams 87 to eifcct thenecessary transfers and the pinions restore the transfer pawls whichhave beentripped by the engagement of the approaching tooth on thepinion of neXt lower order with the nose 91 of the adja' cent trippingpaWl 92, to untripped position. At the very beginning of the operationof the machine all of the indicators are restored to zero position bythe oscillation of the arms 212 supporting the bar 213, caused by thecam groove 210 through the pitman 208, the arm 206, the segment rack205, and the pinion 203. unit of movement of the actuators, the cam 196,through thelriding of the roller 194 on the pitman 193 in the rack 195,rocks each coupling pinion 186 into mesh with its ad` jacent gears 182and 184 and causing the differential movement of the actuators to beimparted to the indicators to indicate the amount of the transaction.Before the return movement of the disk 28 is begun the coupling pinions186 are rockedout of enga'gement with the adjacent gears 182 and 184 andthe actuators are returncdto normal position Without affecting theindicators.

. As the pinions 33, mounted on the same sleeve `144 as are the typecarriers, are cons tinuously in mesh with the differential ac- `ist-tuators, the movement ofthe actuators `is imparted to the typecarriers. After the time for the differential movement of the gears haselapsed and before the return movement of the actuators is to takeplace, the platen 184 forced into contact ,with the detail strip 110 totake a'n impression on the detail strip from the type carriers by thereciprocation ofthe pitman 155 as the cam plate 154 on the pitmanco-acts With the inclined edge 152 of the platen carrying bar 149. Thisreciprocation of the pitman 155 also feeds the detail strip one stepthrough the oscillation of the arm 172 carrying the paWl 173 engagingwith the ratchet 169 integral with the paper storage roll 168.

In operating the machine for taking a After the first one-half icombination With a drivenm'ember,

Thisshifts the yoked pitman 112a and the arm 131 on the pitman is taken outof engagement With the stud 134 on the arm 135 and the n'otch 132 on theother arm 130 of this pitman is brought into alinement with the stud 136on the arm 137 fast to the rock shaft 29 so that when the drive shaft 35is rotated 92 and thereby disconnect the latch plate 40 from the disk38,as such engagement forces` the lever 96 downward and movesy the `arm 99rearward, the forward Wall of the recess 140 in this arm being inengagement With the pin 141 on the latch. In this Way the differentialmovement ofthe actuators in total taking operations is controlled by themovement of the counter pinions in moving' reversely to zero position.
